Origin
It was first recorded in 1710.
Explanation
This is a piece of advice which means that one should not concentrate all efforts and resources in one area as one could lose everything. It means not to make everything dependent on only one thing; to place all one’s resources in one place, account, etc. (If the basket is dropped, all is lost.). It is to risk your money or your reputation in support of one idea or plan. It is based on the idea that if all the eggs you got from your chickens are in one basket ( container) and you drop it, you will lose all your eggs. Don’t risk everything on the success of one venture. Don’t count on any one thing to keep what is valuable or safe. It is the same as ‘He is a fool who will adventure all his goods in one ship’.
Examples
Mr Tan’s financial adviser urged him to be careful and not put all his eggs in one basket by investing all his money in stocks.
I advise you to diversify and not to put all your eggs in one basket.
I didn’t want to put all my eggs in one basket, so I played five different lottery games, but lost all of them.
If you are saving for your retirement, you should make sure that you don’t put all your eggs in one basket. Make sure you put some money into stocks, mutual funds, and bonds.
